IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 142,707, datedSeptember 9, 1873; application filed June 24, 1873.

.0 all whom it may concern:

Be it known that we, EZEKIEL G. LITTLE and DAVID H. NATION, of St.Louis, in the county of St. Louis and in the State of Misiouri, haveinvented certain new and useful Improvements in Stoves; and do herebydeelare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings and to thelet- ;ers of reference marked thereon, making a part of thisspecification.

Our invention relates to that class of heatin g-stoves wherein the ovalis made transverse, and the flue is made to encircle the bottom part ofthe oval from side to side; and the nature of our invention consists inthe construction and arrangement of a heating-stove, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichFigure l is a front elevation, Fig. 2 is a transverse vertical section,and Fig. 3 is a longitudinal vertical section, of our stove.

A represents the fire and combustion chamber. Bis the flue encirclingthe lower part of the body of the stove. G is the flue or divisionplate. D is the exit-flue chamber. E is the hearth, extending the wholelength of the body of the stove. F is the hearth-plate, through whichthe draft is admitted. G is the angular plate or gratefront. H is thedamper; I, the exit-pipe; J, the door-frame; and K the door.

The novelty of this invention consists in makinga front of what hasheretofore been a side of an oval heating-stove, by the application of ahearth, E, and a door, K, by which means we are enabled, by the additionof mica or perforated tin, to obtain a beautiful illuminatedparlor-stove; and by admitting the draft at the center of the fire-boxthrough the damper F, we obtain a more perfect combustion of the fuelthan in the ordinary method at one end of the fire-box. Another point ofnovelty is, the construction of the exit-flue chamber D, it being madein two parts, divided at the center, and the flue-plate 0 carriedthrough the outside casin g sufficiently far into the flue-chamber tosupport the damper H at an angle, so that it will stay up when closed,and when open the damper will lie on a horizontal line with the plate.This fluechamber D is made separate from the body of the stove, mountedtogether, and riveted or bolted to the body of the stove.

When the damper H is closed, the heated products of combustion pass overand down the flues each side of the front door-opening or grate-front,making the circuit of the lower part of the body of the stove throughthe flue B into the flue-chamber D, and out of the exit-pipe I. When thedamper H is open or lies on the horizontal line, the heat passesimmediately off into the flue-chamber D and out of the exit-pipe I.

Our invention can be used on stoves having either cast or sheet ironbodies and therefore we do not confine ourselves to either material inthe construction of these stoves.

The object and advantage of this invention are, that we obtain, by theaid of mica or perforated tin, a handsome parlor-stove, and, dividingthe heat by means of the front opening, we effectually heat the outsideof the stove.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

l. The oval heating-stove described, provided with hearth E,hearth-plate F, and mica doors J K on one of its sides, and exit-fluechamber and pipe-opening upon the opposite side, whereby the draft isadmitted at the center of the fire-box, and extends across the narrowportion of the stove, substantially as set forth.

2. In an oval heating-stove, the combination of the flue-sheet G,extended beyond the stove body, the exterior flue-chamber D, and thedamper H with the flue B, all substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our handsthis 23d day of May, 1873.
